Big sound meets big value. Use this flexible KM Six-Channel Marine Amplifier to power your system with ease and pump up the sound like only KICKER can!

Power the Party

Using a Class-D power plant, this amp features a variable bass boost with KickEQ™, giving you as much as 12dB of extra bump. Powering as many as eight speakers, this amplifier makes your entire boat sound like a floating concert! A powerful 12dB crossover is also included, letting you quickly tune your system to perfection.


In the Zone

KICKER created the KMA450.6 to power up to three independent full-range zones! This six-channel, 450-watt amp provides an easy way to get the perfect volume levels on (or off) the deck, in the water, or inside the cabin. Control the volume of one zone with the receiver. Another zone is controlled with the included full-range volume knob, which can be mounted on (or under) nearly any flat surface.



Dialing in your sound is easy with KM amps. Variable 12dB crossovers are built in, plus a 24dB subsonic filter is also included on the KMA600.1 mono amplifier, and Amp 3 of the KMA450.6. The amplifiers are also equipped with the KickEQ™ variable 12dB bass boost!


Top Tech

Purpose-built for your boat, every KM amp comes complete with marine-grade speaker terminals, stainless-steel screws, conformal-coated circuit boards and ABYC/NMMA-compliant power connections.


In the Zone - 450.6

With this KM Six-Channel Amp, your boat is a floating concert!
